Fabrication and optical behaviors of core–shell ZnS nanostructures
Novel core-shell nanostructures comprised of cubic sphalerite and hexagonal wurtzite ZnS have been synthesized at 150°C by a simple hydrothermal method. The results of HR-TEM and SAED investigation reveal that the cores of hexagonal wurtzite ZnS (ca. 200 nm in average diameter) are encapsulated by a shell of cubic sphalerite ZnS. The FE-SEM image of the nanomaterials shows a surface tightly packed with nanoparticles (<10 nm in size). The optical properties of the fabricated material have been studied in terms of ultraviolet-visible absorption and photoluminescence. Furthermore, a possible mechanism for the fabrication of the core-shell nanostructures has been presented. © The Author(s) 2010.
